I would also recommend the Chicken Soup for the Puppy Lover's Soul and either Plush Puppy or Chris Christensen Shampoos and conditioners. Also the Cowboy Magic detangler & shine is good. I haven't yet tried the Missing Link but certainly intend to as it is highly recommended by many whose advice I respect.
If your baby is that small, I would also recommend you keep some Nutrical on hand at all times. You really need to watch one that small for hypoglycemia at all times.
Good luck.
